Ruthenium is very rare shiny metal and one of transition metals. It was discovered in Russia and named after the Latin name of that country. Only very small doses of ruthenium can be found on our planet, usually in compounds with other metals like platinum or nickel. This metal is used in alloys with other metals and it produces a large number of compounds like oxides, halides, etc. The alloys with platinum and palladium are characterized by very high strength and can be used in electrical contacts, chips, etc. This element is sometimes used as a catalyst, in particular, for producing ammonia. Some compounds of ruthenium can be used in jewelry and producing equipment for transforming solar energy in electricity.
